Prescribing information for all COVID-19 vaccines currently being used in Ireland
Class information is based on the vaccines currently being used in Ireland. In order to improve traceability of biological medicinals, clearly record the name and the batch number of the administered product.
Contraindications (CI): Hypersensitivity to any member of the class, vaccine component, trace substances after manufacture or following previous admin of a similar vaccine. Use of live viruses with immunosuppression (chemo- or radiotherapy, organ or bone marrow transplantation and/or currently on immunosuppressives including corticosteroids); impaired cell-mediated immunity (HIV infection, Severe Combined Immunodeficiency Syndrome, Di George Syndrome or congenital/hereditary immunodeficiency; severe humoral or cellular, primary or acquired immunodeficiency).
Special Precautions (SP): Hypersensitivity and anaphylaxis. Appropriate medical treatment and supervision to be available in case of anaphylactic reaction. Close observation for minimum 15 minutes after vaccination.
Anxiety-related reactions e.g. vasovagal reactions (syncope), hyperventilation or stress-related reactions (dizziness, palpitations, increased heart rate, altered blood pressure, paraesthesia, hypoaesthesia, sweating) may occur in association with the vaccination process itself. Usually temporary and resolve on their own. Advise vaccinees to bring symptoms to attention of vaccination provided to evaluate. Ensure precautions to avoid injury from fainting.
Concurrent illness, postpone (acute severe febrile illness, acute infection); do not delay (minor infection, low-grade fever).
Thrombocytopenia, any coagulation disorder, individuals receiving anticoagulants, weigh risk/benefit of using IM route (bleeding or bruising may occur following IM admin). Vaccines may not protect 100% of recipients; reduced immunogenicity in immuno-compromised (immunosuppressive therapy, genetic causes). Duration of protection is still being determined by ongoing clinical trials.
Driving: Possible side-effects may affect ability. Do not drive if feeling unwell after vaccination.

Latest Safety Assessments

The EMA published its final safety update on COVID-19 vaccines in December 2022. The EMA continues to monitor and assess safety data on COVID-19 vaccines as it does for all medicines authorised in the EU.

  • Menstrual Bleeding: For Comirnaty and Spikevax, an update to the product information has been recommended to add heavy menstrual bleeding as a side effect.
  • Urticaria: For Spikevax, a further update to the product information has been recommended to include urticaria as an uncommon side effect (i.e., occurring in less than 1 in 100 persons). 
  • Corneal graft rejection (CGR): Available evidence does not support a causal relationship of CGR with Comirnaty, Spikevax or Vaxzevria. [08 September 2022].
  • Myocarditis and pericarditis: Update to the product information. In December 2021, PRAC concluded that the risk of myocarditis and pericarditis (inflammatory conditions of the heart) after vaccination with Comirnaty is highest in young males, especially after the second vaccination (see safety update of December 2021). Overall, there is a very rare risk of myocarditis and pericarditis following vaccination with Comirnaty regardless of dose. [08 September 2022].
    PRAC has continued monitoring this risk and assessed recent data, including a US study that analysed data from three safety monitoring systems. Based on this new information, PRAC has recommended an update to the EU product information to state that the risk of myocarditis and pericarditis seems lower in children aged 5-11 years than in those aged 12-17 years. The overall frequency category of myocarditis/pericarditis is already described in the product information as very rare (i.e. occurring in less than 1 in 10,000 persons vaccinated).
  • Vulval ulceration: Assessment started. A very small number of cases of vulval ulceration will be assessed to determine whether they may have been caused by Comirnaty. Vulval ulcerations are usually self-limiting sores on the outer parts of the female genitals. Reported cases concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. [08 September 2022].
  • Histiocytic necrotising lymphadenitis: Monitored within routine safety surveillance. A very small number of cases of histiocytic necrotising lymphadenitis (HNL) will be further monitored and assessed within the regular safety surveillance of Comirnaty. HNL is a condition involving swollen lymph nodes, mild fever and night sweats, and is usually transient and self-limiting. Reported cases concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. [08 September 2022].
  • Myocardial infarction, pulmonary embolism and thrombosis: Available evidence does not support a causal relationships with Vaxzevria. [17 June 2022].
  • Myocarditis and pericarditis: An assessment of myocarditis and pericarditis (inflammatory conditions of the heart) has been started, to establish whether these may be side effects of Nuvaxovid. [17 June 2022]. In July 2022, it was noted that the Australian Therapeutic Goods Administration (TGA) recently added pericarditis (inflammation of lining around the heart) to the product information as a side effect of unknown frequency. Only a small number of myocarditis and/or pericarditis cases have been reported spontaneously with use of Nuvaxovid in the EU (5 EU/EEA cases reported by 31 May 2022 from about 210,000 vaccine doses administered in the EU/EEA by 15 May 20223). Generally, cases reported spontaneously by a patient or healthcare professional concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. Additional information and further data has been requested from the marketing authorisation holder to finalise assessment of myocarditis and pericarditis.
    Symptoms of myocarditis and pericarditis can vary but often include breathlessness, a forceful heartbeat that may be irregular (palpitations), and chest pain. These conditions can have various causes, including viral infection as a common cause and, less commonly, autoimmune disorders. Persons experiencing the above symptoms should seek immediate medical attention to obtain treatment.
  • Myocardial infarction: Available evidence does not support a causal relationship of myocardial infarction with Jcovden. [17 June 2022].
  • Amenorrhoea and heavy menstrual bleeding: Available evidence does not support a causal relationship of amenorrhoea with Comirnaty and Spikevax; the assessment of heavy menstrual bleeding is ongoing. [17 June 2022].
  • Auto-immune hepatitis (AIH): No evidence for a causal relationship with Comirnaty or Spikevax. An assessment of whether vaccination with Comirnaty or Spikevax can cause auto-immune hepatitis (AIH) has been completed. EMA-PRAC has concluded that the currently available evidence does not support a causal association between the vaccines and this condition. [12 May 2022].
  • Corneal graft rejection (CGR): Assessment started for Comirnaty, Spikevax and Vaxzevria. EMA-PRAC started an assessment of corneal graft rejection (CGR) to establish whether it may be a side effect of COVID-19 vaccines (Comirnaty, Spikevax and Vaxzevria). CGR occurs when the body’s immune system mistakenly attacks the donor cornea (the transparent layer in front of the eye) that has replaced a damaged or diseased one. The assessment follows a very small number of cases of CGR reported after vaccination with Comirnaty, Spikevax and Vaxzevria in the medical literature and EudraVigilance. Reported cases concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. [12 May 2022].

All Updates

The EMA published its final safety update on COVID-19 vaccines in December 2022. The EMA continues to monitor and assess safety data on COVID-19 vaccines as it does for all medicines authorised in the EU.

Comirnaty COVID-19 Vaccine (Pfizer)

Safety Update (EMA 08 December 2022): Based on continuous safety monitoring and assessments, there are currently no updates to the product information of Comirnaty.
Safety Update (EMA 10 November 2022): PRAC has recommended that heavy menstrual bleeding should be added to the Comirnaty product information as a side effect of unknown frequency. The conclusion was based on evidence including cases reported during clinical trials, observational studies, intensified post-marketing surveillance activities and spontaneously reported cases by patients and healthcare professionals, including from European countries, present in EudraVigilance. The assessment included almost 9,000 worldwide reports of heavy menstrual bleeding with either Comirnaty or Spikevax (both mRNA vaccines). The frequency category assigned is ‘not known’, as it is generally difficult to robustly estimate side effect frequencies from spontaneously reported cases of suspected side effects. In general, cases reported spontaneously by a patient or healthcare professional concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. Heavy menstrual bleeding (heavy periods) may be defined as bleeding characterised by an increased volume and/or duration which interferes with the person’s physical, social, emotional and material quality of life. Cases of heavy menstrual bleeding have been reported after the first, second and booster doses of Comirnaty. A small number of cases involved positive rechallenge (where heavy menstrual bleeding was seen after the initial vaccination and occurred again after a second dose). A positive rechallenge may indicate that a medicine may have caused the side effect in question. The available data reviewed involved cases that were mostly non-serious and temporary. After reviewing the data, the Committee concluded that there is at least a reasonable possibility that heavy menstrual bleeding is causally associated with Comirnaty and therefore recommended updating the product information. There is no evidence to suggest that menstrual changes experienced by some people following vaccination have any impact on fertility. With regard to the effects of COVID-19 vaccination on pregnancy in general, several studies involving around 65,000 pregnancies at different stages did not find any sign of an increased risk of pregnancy complications, miscarriages, preterm births or adverse effects in the unborn babies following mRNA COVID-19 vaccination.
Safety Update (EMA 06 October 2022): There are no safety updates.
Safety Update (EMA 08 September 2022): The EMA Pharmacovigilance Risk Assessment Committee (PRAC) has recommended an update to the
EU product information to state that the risk of myocarditis and pericarditis seems lower in children aged 5-11 years than in those aged 12-17 years. The overall frequency category of myocarditis/pericarditis is already described in the product information as very rare (i.e. occurring in less than 1 in 10,000 persons vaccinated).
Safety Update (EMA 14 July 2022, updated 03 August 2022): There are currently no safety updates.

Safety Update (EMA 18 June 2021): Reports of inflammation of the heart muscle (myocarditis) and membrane (pericarditis) in a small number of people after vaccination continue to be assessed under an accelerated timetable. There are no updates to the product information. Comirnaty is effective in preventing COVID-19. 
More Flexible Storage Conditions (EMA 17 May 2021): The EMA human medicines committee (CHMP) has recommended a change to the approved storage conditions that will facilitate the handling of the vaccine in vaccination centres across the European Union (EU). The changes described will be included in the publicly available information on and will be implemented by the MAH in updated product labelling. Users are reminded to always refer to the label and package leaflet of the supplied product for the correct storage information. This change extends the approved storage period of the unopened thawed vial at 2-8 deg C (i.e. in a normal fridge after taking out of deep-freeze conditions) from five days to one month (31 days). The change was approved following assessment of additional stability study data submitted to EMA by the marketing authorisation holder (MAH). Increased flexibility in the storage and handling of the vaccine is expected to have a significant impact on planning and logistics of the vaccine roll-out in EU Member States. 
Safety Update (EMA 11 May 2021): Swelling of the face in people who have had a dermal filler injection will be added to the product information of Comirnaty as a side effect. Case reports of inflammation of the heart muscle and membrane will be further assessed.

 Spikevax COVID-19 Vaccine (previously Moderna COVID-19 Vaccine) (Moderna)
 
Safety Update (EMA 08 December 2022): Based on continuous safety monitoring and assessments, there are currently no updates to the product information of Spikevax
Safety Update (EMA 10 November 2022): PRAC has recommended that heavy menstrual bleeding should be added to the Comirnaty product information as a side effect of unknown frequency. The conclusion was based on evidence including cases reported during clinical trials, observational studies, intensified post-marketing surveillance activities and spontaneously reported cases by patients and healthcare professionals, including from European countries, present in EudraVigilance. The assessment included almost 9,000 worldwide reports of heavy menstrual bleeding with either Comirnaty or Spikevax (both mRNA vaccines). The frequency category assigned is ‘not known’, as it is generally difficult to robustly estimate side effect frequencies from spontaneously reported cases of suspected side effects. In general, cases reported spontaneously by a patient or healthcare professional concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. Heavy menstrual bleeding (heavy periods) may be defined as bleeding characterised by an increased volume and/or duration which interferes with the person’s physical, social, emotional and material quality of life. Cases of heavy menstrual bleeding have been reported after the first, second and booster doses of Comirnaty. A small number of cases involved positive rechallenge (where heavy menstrual bleeding was seen after the initial vaccination and occurred again after a second dose). A positive rechallenge may indicate that a medicine may have caused the side effect in question.The available data reviewed involved cases that were mostly non-serious and temporary. After reviewing the data, the Committee concluded that there is at least a reasonable possibility that heavy menstrual bleeding is causally associated with Spikevax and therefore recommended updating the product information. There is no evidence to suggest that menstrual changes experienced by some people following vaccination have any impact on fertility. With regard to the effects of COVID-19 vaccination on pregnancy in general, several studies involving around 65,000 pregnancies at different stages did not find any sign of an increased risk of pregnancy complications, miscarriages, preterm births or adverse effects in the unborn babies following mRNA COVID-19 vaccination.
The PRAC concluded an assessment of the hypersensitivity reaction urticaria (hives [raised, red and itchy skin rash]) with Spikevax. After reviewing the data, the Committee concluded that there is at least a reasonable possibility that urticaria is causally associated with Spikevax and therefore recommended updating the product information. The Committee recommended that urticaria should be added to the product information as a side effect of uncommon frequency (occurring in less than 1 in 100 people). Urticaria has been observed with either acute onset (within a few days after vaccination) or delayed onset (up to approximately two weeks after vaccination). 
Safety Update (EMA 06 October 2022):  Assessment ongoing. An assessment of the potential hypersensitivity reaction urticaria (hives [raised, red and itchy skin rash]) with Spikevax remains ongoing.
Safety Update (EMA 08 September 2022): PRAC assessment concluded that the available evidence does not support a causal relationship of corneal graft rejection with Spikevax. Update to the product information. PRAC concluded that the risk of myocarditis and pericarditis (inflammatory conditions of the heart) after vaccination with Spikevax is highest in young males, especially after the second vaccination. The product information of Spikevax has been updated to reflect that the risk profile for myocarditis and pericarditis seems to be similar after the second and the third dose. The overall frequency category of myocarditis/pericarditis is already described in the product information as very rare (i.e. occurring in less than 1 in 10,000 vaccinated persons).
Safety Update (EMA 14 July 2022, updated 03 August 2022): Extensive swelling of the vaccinated limb will be included in the EU product information as a side effect of Spikevax. The frequency category will be ‘not known’, as it is generally difficult to robustly estimate side effect frequencies from spontaneously reported cases of suspected side effects.
Cases of extensive swelling of the vaccinated limb have been reported spontaneously with use of Spikevax (more than 3,200 EU/EEA cases reported to EudraVigilance (see section 2) by 2 May 2022). Generally, cases reported spontaneously by a patient or healthcare professional concern suspected side effects, i.e. medical events that have been observed after vaccination, but which are not necessarily related to or caused by the vaccine. In general, extensive swelling of the vaccinated limb is a condition that does not require treatment and resolves after some days.

Class information is based on the vaccines currently being used in Ireland. In order to improve traceability of biological medicinals, clearly record the name and the batch number of the administered product.
Contraindications (CI): Hypersensitivity to any member of the class, vaccine component, trace substances after manufacture or following previous admin of a similar vaccine. Use of live viruses with immunosuppression (chemo- or radiotherapy, organ or bone marrow transplantation and/or currently on immunosuppressives including corticosteroids); impaired cell-mediated immunity (HIV infection, Severe Combined Immunodeficiency Syndrome, Di George Syndrome or congenital/hereditary immunodeficiency; severe humoral or cellular, primary or acquired immunodeficiency).
Special Precautions (SP)P: Hypersensitivity and anaphylaxis. Appropriate medical treatment and supervision to be available in case of anaphylactic reaction. Close observation for minimum 15 minutes after vaccination.
Anxiety-related reactions e.g. vasovagal reactions (syncope), hyperventilation or stress-related reactions (dizziness, palpitations, increased heart rate, altered blood pressure, paraesthesia, hypoaesthesia, sweating) may occur in association with the vaccination process itself. Usually temporary and resolve on their own. Advise vaccinees to bring symptoms to attention of vaccination provided to evaluate. Ensure precautions to avoid injury from fainting.
Concurrent illness, postpone (acute severe febrile illness, acute infection); do not delay (minor infection, low-grade fever).
Thrombocytopenia, any coagulation disorder, individuals receiving anticoagulants, weigh risk/benefit of using IM route (bleeding or bruising may occur following IM admin). Vaccines may not protect 100% of recipients; reduced immunogenicity in immuno-compromised (immunosuppressive therapy, genetic causes). Duration of protection is still being determined by ongoing clinical trials.
Driving: Possible side-effects may affect ability. Do not drive if feeling unwell after vaccination.

ATC Code: J07BX03.
 
Indication(s): Active immunisation to prevent COVID-19 disease caused by SARS-CoV-2 virus from age 18 years (JCOVDEN, Vaxzevria) OR age 12 years (Nuvaxovid).                       
Dose, Adult: From age 18 years, JCOVDEN, admin as a single dose (0.5mL). Booster (second dose), of 0.5 mL may be admin IM at least 2 months after the primary vaccination; may admin as a heterologous booster dose completion of primary vaccination with an approved mRNA COVID-19 vaccine (dose interval same as for vaccine used in primary schedule).
From age 18 years, Vaxzevria, admin as a 2-dose course (0.5mL each), between 4 and 12 weeks (28-84 days) apart. Booster (third dose) of 0.5mL may be admin at least 3 months after primary vaccination; may be admin to individuals who completed the primary vaccination course with Vaxzevria or an mRNA COVID-19 vaccine.
From age 12 years, Nuvaxovid, admin as a 2-dose course (0.5mL each), 3 weeks after first dose. From age 18 years, booster (third dose), of 0.5mL may be admin IM at approx. 6 months after the primary vaccination; may admin as a heterologous booster dose completion of primary vaccination with an approved mRNA COVID-19 vaccine or adenoviral vector vaccine (dose interval same as for vaccine used in primary schedule).
Admin, IM injection ONLY, preferably deltoid muscle of upper arm. NOT for IV, SC or intradermal injection.
Dose, Elderly: No dose adjustment.    
Dose, Child: Age 18 years and older (JCOVDEN, Vaxzevria) OR 12 years and older (Nuvaxovid), as for Adult. Under 18 years (JCOVDEN, Vaxzevria) OR under 12 years (Nuvaxovid), safety and efficacy not established.                
Contraindications: Thrombosis with thrombocytopenia syndrome (TTS) following vaccination; previous episodes of capillary leak syndrome (CLS) (JCOVDEN, Vaxzevria).   
Interactions: Effect of Other Drugs on COVID-19 rDNA Vaccines:  No interaction studies performed. The binding antibody response to SARS-CoV-2 was lower when Nuvaxovid was co-admin with inactivated influenza vaccine (clinical significance unknown).                      
Special Precautions: Individuals vaccinated may not be fully protected until 14 days after single dose vaccination (JCOVDEN) OR 15 days (Vaxzevria) OR 7 days (Nuvaxovid) after the second dose. Duration of protection is still being determined by ongoing clinical trials.
JCOVDEN, Vaxzevria, thrombosis with thrombocytopenia syndrome (rare), some cases with bleeding, post-vaccination, including severe cases presenting as venous thrombosis at unusual sites e.g. cerebral venous sinus thrombosis, splanchnic vein thrombosis and arterial thrombosis, with thrombocytopenia (some cases fatal). Majority occurred within first 3 weeks post-vaccination, mostly in women (both brands) under age 60 years (JCOVDEN). Thrombosis with thrombocytopenia requires specialised clinical management; consult guidance and/or consult specialists e.g. haematologists, coagulation specialists to diagnose and treat.
JCOVDEN, Vaxzevria, very rarely reported, Guillain-Barré syndrome (GBS) following vaccination. H/care professionals to be alert for GBS signs and symptoms; ensure correct diagnosis (or rule out other causes) and initiate adequate supportive care and treatment. Capillary leak syndrome (CLS) in first days post-vaccination; some cases fatal. CLS characterised by acute episodes of oedema (mainly limbs), hypotension, haemoconcentration, hypoalbuminaemia. Acute CLS episode following vaccination requires prompt recognition, treatment. Intensive supportive therapy usually needed. Do not vaccinate with known CLS history.
Anxiety-related reactions, concurrent illness, thrombocytopenia, coagulation disorders, see Class Effects.
Pregnancy, Lactation: Weigh risk/benefit. Unknown if excreted in human milk.      
Adverse Reactions: Summary, most frequent (all brands), injection site pain, headache, fatigue, myalgia, nausea. Reactogenicity was generally milder and reported less frequently in older adults.
Additional adverse reactions, JCOVDEN, pyrexia; most reactions were mild to moderate and of short duration (1-2 days). Nuvaxovid, injection site tenderness, arthralgia, malaise, vomiting; reactions were usually mild to moderate, of duration under 2 days (local events) or 1 day (systemic events). Vaxzevria, pyrexia, injection site tenderness, malaise, chills, arthralgia; most reactions were mild to moderate and usually resolved within a few days; those reported after the second dose were milder and reported less frequently.
